Abstract
The utility model discloses a tensioning mechanism with a belt assisting, and belongs to the field of engineering machinery. The shortcomings that a belt of a belt tensioning mechanism in the prior art is not convenient and locking of the belt is not reliable are overcome. The technical scheme is that the tensioning mechanism with the belt assisting comprises a fixing block, a tensioning bolt and a fixing bolt. The fixing block is fixedly provided with a flange and a boss, a threaded hole A and a threaded hole B are formed in the fixing block, the tensioning bolt is arranged inside the threaded hole A, and the fixing bolt is arranged inside the threaded hole B. The tensioning mechanism is mainly used for the tensioning device of a belt pulley of an engine.
Description
Technical field
The utility model belongs to a kind of engineering mechanical components, specifically, relates in particular to the auxiliary Fastening mechanism of a kind of belt.
Background technique
On excavator or loader, the generator power of a lot of motors all utilizes belt transmission, use the belt transmission just to need belt tension mechanism, a kind of traditional Fastening mechanism is exactly the sliding york Fastening mechanism with the tighting rod of chute, the characteristics of this structure are that tighting rod one end is fixed on the body fixed base, the other end is a chute, clamping bolt can have relative movement with chute, cause generator (or compressor) to rotate around the axis when imposing external force, when reaching the position of belt tension requirement, tight a bolt.Although this structure is simple, has following two shortcomings: 1. tensioner inconvenience, clamping bolt again after need to generator being pinned by instruments such as crowbars; 2. it is unreliable to lock, and machine run is after a period of time, and bolt is easily loosening.
The model utility content
The utility model purpose provides the auxiliary Fastening mechanism of a kind of belt, to overcome the inconvenient and insecure defective of locking belt of belt tension mechanism tensioner belt in the prior art.
For overcoming defects, the utility model has adopted following technological scheme: a kind of belt is assisted Fastening mechanism, comprise fixed block, tension bolt and fixing bolt, be fixed with flange and boss on the described fixed block, have tapped hole A and tapped hole B on the fixed block, described tension bolt is assemblied in the tapped hole A, and described fixing bolt is assemblied in the tapped hole B.
Described tension bolt is provided with locking nut and elastic washer, and described bolt assembly B is provided with elastic washer, big flat washer.
Compared with prior art, the beneficial effects of the utility model are: (1) need not by extra instrument, and the tensioner belt is convenient; (2) increased locking mechanism one in original belt tension mechanism, belt position locking is more reliable.
Description of drawings
Fig. 1 is the utility model erection drawing;
Fig. 2 is the utility model perspective view;
Fig. 3 is use phase diagram of the present utility model.
Among the figure: 1, tension bolt; 2, locking nut; 3, fixed block; 4, big flat washer; 5, bullet pad; 6, fixing bolt; 7, tapped hole A; 8, tapped hole B; 9, boss; 10, flange; 11, connecting bolt; 12, tighting rod; 13, fixed base; 14, rotating shaft.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Such as Fig. 1, shown in Figure 2, the utility model adds the auxiliary Fastening mechanism of a kind of belt on the basis of former belt Tensioning structure, the auxiliary Fastening mechanism of described belt comprises tension bolt 1, fixed block 3 and fixing bolt 6, be fixed with boss 9 and flange 10 on the fixed block 3, be designed with tapped hole A7 and tapped hole B8 on the fixed block 3 simultaneously, tapped hole A7 is used for assembling tension bolt 1, tension bolt 1 is provided with locking nut 2 and bullet pad 5, tapped hole B8 is fixed on fixed block 3 on the former belt Tensioning structure by fixing bolt 6, is provided with bullet pad 5 and big flat washer 4 between fixing bolt 6 and the fixed block 3.
As shown in Figure 3, fixed block 3 is fixed on the tighting rod 12 by fixing bolt 6, bullet pad 5 and big flat washer 4, again tension bolt 1 is assembled on the fixed block 3, the flange 10 of design and boss 9 are connected with tighting rod 12 on the fixed block 3, the projection of fixed block 3 cooperates with the chute of tighting rod 12 and is adjacent to, the height of boss 9 can not surpass the thickness of tighting rod 12, just push up on upper generator (compressor etc.) fixed ear base with the bottom of tension bolt 1 and to be advisable, at this moment tension bolt 1 is locked on the fixed block 3 by locking nut 2 and bullet pad 5.
When belt is loosening, can unclamp connecting bolt 11 and nut 2, twist clockwise tension bolt 1, the bottom of tension bolt 1 pushes generator and rotates to the tensioner direction, when treating that belt reaches the tensioner requirement, just stop to twist tension bolt 1 and pass through locking nut 2 lockings, and be fastenedly connected simultaneously bolt 11, the position of locking motor.Well solved the inconvenient and insecure problem of locking of tensioner by increasing said mechanism.
Claims (2)
1. a belt is assisted Fastening mechanism, it is characterized in that: comprise tension bolt (1), fixed block (3) and fixing bolt (6), be fixed with boss (9) and flange (10) on the described fixed block (3), fixed block has tapped hole A(7 on (3)) and tapped hole B(8), described tension bolt (1) is assemblied in tapped hole A(7) in, described fixing bolt (6) is assemblied in tapped hole B(8) in.
2. belt according to claim 1 is assisted Fastening mechanism, and it is characterized in that: described tension bolt (1) is provided with locking nut (2) and bullet pad (5), and described fixing bolt (6) is provided with bullet pad (5), big flat washer (4).
